After upgrading to Mac OSX Mountain Lion, each time I open Dreamweaver CS5.5 I have to enter my remote server's username and password. The Save password checkbox is checked. Everything works fine during that session but if I close Dreamweaver and reopen it, I find it hasn't retained that username and password. The problem happens 100% of the time. I've seen this same problem with a few other people but no solutions yet. Any idea?

That's a corrupt keychain, nothing to do with Adobe. Happened to me after the Apple Lion upgrade with some applications.

First open up the Keychain app in the Utitilies folder (or hit cmd+space for spotlight and type "keychain" it will be first). Then in the search box at the top of Keychain, type "SiteServer". That will bring up the DW passwords. If you don't know your passwords, open each up and write them down. Once you know them, delete the records that came up from your search. Then proceed to open DW. All passwords will now be gone and you will have to go through your site's 1-by-1 and re-add the passwords. The site definitions will still be in tact, only the passwords will have to be re-saved since DW uses the Apple keychain to store passwords and not the configuration files. Close DW and re-open again, your passwords should be good to go.

I am having the issue of just not being able to connect to the servers at all now that I have Mountain Lion installed with CS5.5

I can, however, connect to the servers with cyberduck, so I know this must be an issue with Dreamweaver. Any help would be appreciated. I did notice a patch for this issue in cs6, but unfortunately not for cs5.5

Thanks SnakEyez. I did as you suggested but with no luck. I deleted all of the DW sites from Keychain, entered them into DW, connected, signed off and closed DW. When I opened DW again the server username and passwords were once again blank. When I checked in Keychain the few that I had reentered were listed with the proper username and password.

Nope, no luck. Did both steps 4 & 12, did the Repair Permissions, reopened DW, put in the username and password, and connected. I then shut DW, reopened it and couldn't connect because the server username and password were missing.

Try going back to Keychain Access and click on Keychain Access -> Keychain First Aid and run the repair tool. Also verify in the "SiteServer" keys that DW leaves that the access control says DW CS5.5 and no other versions (unless you are actively using those other versions). I've run into issues before where there were multiple versions listed in there.

Ran the repair tool and checked the siteserver keys which did have access control set for DW CS5. I am using DW CS5.5 so I tried adding to the list by navigating to DW CS5.5 but it appeared again as CS5. Still having the problem.

My last resort solution is usually to create a new user account on the OS and see if passwords still have an issue. I've rarely come across user account corruption. When it happens you typically create a new user account as if that would be your primary. Then you sparingly bring over configuration files from the Library of your old account to the new account trying to eliminate where ever the corruption was. If this doesn't work, there's not much I can say other than to file a bug report or upgrade.

FYI, I am having the exact same issue. My problem ended up being the same, after fixing my connection issue with SnakEyez help yesterday, my login credentials refuse to stay saved. So, for now, I will be simply putting them in daily or leaving my computer on.

I have a hard time believing that it is simply an issue with keychain because of the steps you've went through and because not a single other app is having the issue. However, I will continue to follow your progress on the issue and hope you find what you're looking for.

I'm having exactly the same issues with only DreamWeaver CS 5.5 too (it's an infinetly buggy app, always has been on both Windows and Mac). It's definitely an Adobe DW CS5.5 / Mountain Lion issue that needs to be addressed by Adobe, but triggered by an upgrade to Mountain Lion. Opening up the passkey permissions to all applications doesn't fix the problem.

I have not yet tried that, but I will soon. I noticed that even when I go to my lock screen the login credentials clear from the servers. In fact, I will go ahead and try creating a new account now, though I do not feel that would be a viable solution for long term.

I had actually tried creating a new account earlier due to some additional issues I am having with Mountain Lion permissions, so that didn't do anything.

No, when you look at the Keychain, it is set up correctly for the application, but somehow it's not getting back from the keychain to the application (like it did in Lion). This is one of those cases where Apple will blame Adobe, and Adobe will balme Apple and a couple months down the line there will be two quiet updates that pass in the night so that everyone can save face.

I think, based on my regrettable experience upgrading to Mountain Lion, that Apple folks are scrambling right now, plugging holes in what has been a pretty ill-planned update (from my perspective, anyway).

Actually, looked at the above symptoms and potential solutions. Have EXACTLY the same problem and have done all of the above.

Can only conclude that the Mountain Lion/Dreamweaver CS5.5 combination results in the wretched username/password isn't remembered and on subsequent log-ins to remote server won't even accept the right details.

Fetch accesses the site of course everytime with no problems whatsoever.

Found this happened under Lion a couple of times but not as much as this. SURELY Adobe you can sort this one out very easily or is CS5.5 too old for you to fix it? Is there a similar problem with Dreamweaver CS6???

I had the same problem using Dreamweaver CS4 now that I have upgraded from Snow Leopard to Mountain Lion on my new 2012 iMac. Luckily I had exported my definitions with user id and password, for my web sites. I thought I would try just importing the exported site definitions and voila, it worked. The user ID and password was saved wen I left Dreamweaver.

If you are currently not exporting your site definitions with user id and password, I strongly suggest you start.
